The Hornet-class carrier was a large warship developed by SoroSuub Corporation prior to the Invasion of Naboo. It is considered a Frigate analogue. 
The ship was readily identifiable by its slim design and bridge mounted near the center of its bulk. Some were equipped with baffled ion engines to reduce their sensor profiles.
A pair of these vessels supported a squadron of Z-95 Headhunters and droid fighters in an attack on Station TFP-9 intended to capture several Naboo N-1 fighters and police cruisers.
